5 3 Overview Overview The VM-10xl is a high quality 1:10 video audio distribution amplifier using BNC connectors for composite video, and RCA connectors for unbalanced stereo audio signals. The VM-10xl accepts a composite video input and distributes the signal to 10 identical outputs. In particular, the VM-10xl: Includes looping connectors for connecting to a local monitor, other acceptor, or for forming larger systems 1 Has a video bandwidth of 360MHZ, ensuring transparent performance with typical video and audio sources Can function as unbalanced stereo audio or balanced 2 mono audio (selected via an audio control button) Can output video signals that are DC or AC coupled for maximum flexibility (selected via a coupling button) Has front panel video trimmer controls 3 for output level and cable equalization (EQ.), as well as audio trimmer controls for left and right gain, with an enable / disable control button Achieving the best performance means: Connecting only good quality connection cables, thus avoiding interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables) Avoiding interference from neighboring electrical appliances and positioning your VM-10xl away from moisture, excessive sunlight and dust 4 Your VM-10xl Video Audio Distribution Amplifier Figure 1 and Table 1 define the VM-10xl Video Audio Distribution Amplifier: 1 For example, you can connect 3 VM-10xl units to make a 1:30 video audio distribution amplifier. See section 6.2 for details 2 Recommended for low signal transmission over long distances or in audio broadcasting studios for high quality signal recreation 3 The video outputs are arranged in two blocks of 5 outputs (outputs 1 to 5, and outputs 6 to 10). Each block can be separately trimmed for output level and cable equalization (EQ.) thus achieving different compensations for different cable lengths 3

8 5 Installing on a Rack Installing on a Rack This section describes what to do before installing on a rack and how to rack mount. Before installing on a rack, be sure that the environment is within the recommended range: Operating temperature range +5 to +45 Deg. Centigrade Operating humidity range Storage temperature range Storage humidity range Before Installing on a Rack 5 to 65% RHL, non-condensing -20 to +70 Deg. Centigrade 5 to 95% RHL, non-condensing How to Rack Mount To rack-mount a machine: 1 Attach both ear brackets to the machine. To do so, remove the screws from each side of the machine (3 on each side), and replace those screws through the ear brackets. CAUTION!! When installing on a 19" rack, avoid hazards by taking care that: It is located within the recommended environmental conditions, as the operating ambient temperature of a closed or multi unit rack assembly may exceed the room ambient temperature. Once rack mounted, enough air will still flow around the machine. The machine is placed straight in the correct horizontal position. You do not overload the circuit(s). When connecting the machine to the supply circuit, overloading the circuits might have a detrimental effect on overcurrent protection and supply wiring. Refer to the appropriate nameplate ratings for information. For example, for fuse replacement, see the value printed on the product label. 5 The machine is earthed (grounded) in a reliable way and is connected only to an electricity socket with grounding. Pay particular attention to situations where electricity is supplied indirectly (when the power cord is not plugged directly into the socket in the wall), for example, when using an extension cable or a power strip, and that you use only the power cord that is supplied with the machine. 2 Place the ears of the machine against the rack rails, and insert the proper screws (not provided) through each of the four holes in the rack ears. Note that: In some models, the front panel may feature built-in rack ears Detachable rack ears can be removed for desktop use Always mount the machine in the rack before you attach any cables or connect the machine to the power If you are using a Kramer rack adapter kit (for a machine that is not 19"), see the Rack Adapters user manual for installation instructions (you can download it at: 6 KRAMER: SIMPLE CREATIVE TECHNOLOGY

9 Using the VM-10xl Video Audio Distribution Amplifier 6 Using the VM-10xl Video Audio Distribution Amplifier You can connect: A single VM-10xl unit (see section 6.1) Several VM-10xl units to increase the number of outputs (see section 6.2) 6.1 Connecting a VM-10xl Video Audio Distribution Amplifier You can connect a single VM-10xl Video Audio Distribution Amplifier unit as a 1:10 video audio DA, in which audio is unbalanced stereo audio (left and right) or balanced mono audio (+ and -). To connect the VM-10xl as a 1:10 video unbalanced stereo audio DA, as the example in Figure 2 illustrates, do the following 1 : 1. Connect a video audio source (for example, a composite video player) to the VIDEO IN BNC connector and to the left and right AUDIO IN RCA connectors. 2. Connect 2 the 10 VIDEO OUT BNC connectors and the 10 left and right AUDIO OUTPUT RCA connectors to the video audio acceptors 3 1 to Connect the power cord to the mains electricity. 4. Push in the Term button to terminate the line to Release the BAL/ST button to select unbalanced stereo audio operation. 6. If required, adjust 4 the video trimmer controls 5 for output signal level and/or cable compensation equalization level. 7. If audio control adjustment is required for left and/or right gain, push in Enable/Disable button, and then adjust 6 the trimmer controls. 1 Switch OFF the power on each device before connecting it to your VM-10xl. After connecting your VM-10xl, switch on its power and then switch on the power on each device 2 As required. Up to 10 outputs can be connected on the VM-10xl. Not all outputs need to be connected 3 For example, VCR units 4 Insert a screwdriver into the hole and carefully rotate it, to trim the level 5 The video outputs are arranged in two blocks of 5 outputs (outputs 1 to 5, and outputs 6 to 10). Each block can be separately trimmed for output level and cable equalization (EQ.) thus achieving different compensations for different cable lengths 6 Insert a screwdriver into the hole and carefully rotate it, to trim the level 7

11 Using the VM-10xl Video Audio Distribution Amplifier 6.2 Increasing the Outputs You can increase the number of outputs by interconnecting VM-10xl units. The example in Figure 2 illustrates how to connect 3 units to increase the number of outputs from 10 to 30. To form a 1:30 video and unbalanced stereo audio DA, do the following 1 : 1. Connect a video audio source (for example, a composite VCR) to the VIDEO IN BNC connector and to the left and right AUDIO IN RCA connectors of the first VM-10xl unit. 2. Connect the video LOOP BNC connector of the: First VM-10xl unit to the VIDEO IN BNC connector of the second VM-10xl unit Second VM-10xl unit to the VIDEO IN BNC connector of the third VM-10xl unit 3. Connect the left and right AUDIO LOOP RCA connectors of the: First VM-10xl unit to the left and right AUDIO IN RCA connectors of the second VM-10xl unit Second VM-10xl unit to the left and right AUDIO IN RCA connectors of the third VM-10xl unit 4. Connect the 10 VIDEO OUT BNC connectors and the 10 left and right AUDIO OUTPUT RCA connectors of the: First VM-10xl unit to the video audio acceptors 2 1 to 10 Second VM-10xl unit to the video audio acceptors 2 11 to 20 Third VM-10xl unit to the video audio acceptors 2 21 to On the first and second VM-10xl units, release the Term button. On the third VM-10xl unit, push in the Term button to terminate the line to Switch OFF the power on each device before connecting it to your VM-10xl units. After connecting the VM-10xl units, switch on their power and then switch on the power on each device 2 For example, VCR units 9
